“…Results show a very good linear performance (R=0.99999) of this chip and energy resolutions at the 511 keV peak as good as 12.2% FWHM, which are better than the VATA240 results which showed energy resolutions of 13.2% FWHM [3]. On the right of figure 3 we can also observe the good correlation between the energies deposited on the detector blocks with a PET coincidence trigger.…”

“…We have evaluated the energy resolution of our detectors with VATA241 chip readout by acquiring spectra of 22 Na and 137 Cs radioactive sources. Results show a very good linear performance (R=0.99999) of this chip and energy resolutions at the 511 keV peak as good as 12.2% FWHM, which are better than the VATA240 results which showed energy resolutions of 13.2% FWHM [3].…”

“…Στην κατεύθυνση της κατασκευής μικρών και ευέλικτων συστημάτων απόκτησης δεδομένων αρκετές ομάδες αντικατέστησαν μέρος των αναλογικών ηλεκτρονικών με ψηφιακά ολοκληρωμένα κυκλώματα ειδικού σκοπού (Application Specific Integrated Circuit -ASIC). Συνήθως το συνολικό σύστημα περιλαμβάνει και ένα FPGA για τον έλεγχο των αναλογικών μερών αλλά και για επεξεργασία των σημάτων [70,71,72,73]. Ενώ τα συ-Κεφάλαιο 3.…”
